3.7 Monitored qualitative parameters of E2 optical interface
TM-76 and MD-76 devices are provided with a function of qualitative parameter monitoring.
The devices automatically monitor the linear interface signal parameters and detect, count
and signalize the following conditions and parameters:
Indicators:
•
LOOS
- loss of optical signal
•
LDF
- laser diode failure
•
LOF
- loss of frame synchronization
•
10E-3
- error rate 10
-3
exceeded
•
10E-6
- error rate 10
-6
exceeded
•
RAL
- remote device alarm indicating a remote device connection failure
(between a local and remote device)
•
ES15
- exceeding a 15-minute errored second counter threshold
•
SES15
- exceeding a 15-minute severely errored second counter threshold
•
ES24
- exceeding a 24-hour errored second counter threshold
•
SES24
- exceeding a 24-hour severely errored second counter threshold
•
SESFE15
- exceeding a 15-minute severely errored second far end counter
threshold
•
SESFE24
- exceeding a 24-hour severely errored second far end counter threshold
Counters:
•
